[Apparent immunoreactivity of CRF in the tentacles of the mollusk Helix pomatia].
In the Gastropod Mollusc Helix pomatia (Pulmonata: Stylommatophora), an antiserum raised against ovine CRF 41 reveals a neuropeptide in some primary sensory neurons distributed beneath the epithelium of the higher tentacles (optic) and the lower tentacles. The collar cells and the lateral cells of both kinds of tentacles are innervated by some CRF immunoreactive fibers. Considering the given results, these processes probably originate in the central ganglia, but also in the tentacular sensory neurons. The neuropeptide revealed by our immunserum would be involved in the regulation of the exocrine secretion of the collar and lateral cells. It may also take part in the regulation of the endocrine secretion of collar cells in both sorts of tentacles.
